Description

本発明は、タバコ製品の電気加熱分野に関し、より具体的には、エアチャンネル改良型電気加熱装置に関する。 TECHNICAL FIELD The present invention relates to the field of electrical heating of tobacco products, and more particularly to air channel improved electrical heating devices.

電気で加熱してベークする喫煙方式は、直火で点火して激しく燃焼させるような従来の喫煙方式と異なり、直火燃焼がないので、高温で分解して有害成分を放出するプロセスを省略し、煙中の有害物質の発生量が、従来型タバコが燃焼して生じる有害物質よりも遥かに少なく、将来のタバコ産業の発展方向として有望である。電気加熱では、発熱素子を利用してタバコ製品を加熱し、その香味物質を放出させ、燃焼型タバコ製品と類似したエクスペリエンスを付与する。加熱するときに、タバコ製品がマウスピースの開口端から電気加熱装置の収容室に挿入されるのが一般的であり、空気の給気量及び空気の給気方式が喫煙の品質に大きな影響を与え、現在、電気加熱装置のエアチャンネルのデザインには、下記問題が存在する。すなわち、空気の補充の１つの形態として、空気がシガレットと加熱キャビティとの間で形成された隙間を介して補充され、煙がシガレットを吸うことで放出され、このような方式では、シガレットが加熱キャビティ内で緩まり、冷空気の侵入が抑制できなくなり、喫煙の品質が損なわれ、また、シガレットが点火されてしまうというリスクもある。別の形態として、エアチャンネルが加熱キャビティの内側壁と外側壁との間に設計され、空気が、唇側に近い側の内外側壁の間のスペースを介してキャビティの底部に補充され、次に刻みタバコの端部からシガレットに入り、この場合、経路が長く、喫煙抵抗が大きく、そして、このような構造のデザインのため、クリーニングや使用が複雑になり、使用者のエクスペリエンスが悪い。さらなる形態として、煙が加熱キャビティの外側壁を介して加熱キャビティに直接入り、この場合、加熱する間に煙が給気孔から放出しやすく、煙や煙成分が明らかに損失され、消費エクスペリエンスが悪いという欠陥がある。 Unlike the conventional smoking method that burns by heating with electricity, there is no direct flame combustion, so the process of decomposing at high temperature and releasing harmful components is omitted. , the amount of harmful substances generated in the smoke is far less than that generated by burning conventional cigarettes, and it is a promising direction for the future development of the tobacco industry. Electrical heating utilizes a heating element to heat the tobacco product and release its flavorant, providing an experience similar to combustible tobacco products. When heating, the tobacco product is generally inserted into the storage chamber of the electric heating device from the open end of the mouthpiece, and the amount of air supplied and the air supply method have a great influence on the quality of smoking. Given that, the following problems currently exist in the design of air channels in electric heating devices. That is, in one form of air replenishment, air is replenished through a gap formed between the cigarette and the heating cavity, and smoke is expelled by puffing on the cigarette; There is also the risk that it will loosen in the cavity and the ingress of cold air will become uncontrolled, impairing the smoking quality and the cigarette will be lit. Alternatively, an air channel is designed between the inner and outer walls of the heating cavity, air is replenished to the bottom of the cavity through the space between the inner and outer walls on the lip side, and then The end of the cut tobacco enters the cigarette, where the path is long, the smoking resistance is large, and the design of such a structure complicates cleaning and use, resulting in poor user experience. Another form is that the smoke directly enters the heating cavity through the outer wall of the heating cavity, in which case the smoke is easily emitted from the air supply hole during heating, resulting in obvious loss of smoke and smoke components, and poor consumption experience. There is a flaw.

本発明の目的は、順調に通気でき、ベークするときの空気の補充及び煙の放出を確保し、喫煙の品質を向上させるエアチャンネル改良型電気加熱装置を提供することである。 SUMMARY OF THE INVENTION It is an object of the present invention to provide an improved air channel electric heating device that can be smoothly ventilated, ensure air replenishment and smoke release during baking, and improve smoking quality.
